SetCPU vs. CMSettings Built-in CPU manager

For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?

I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.

I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.

Neither. CPU tuner works best for me.

its the same thing :facepalm:
Try the inbuilt one... I think its way easier

I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?

Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.

I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).

At 1.8Ghz, I find the temp settings in SetCPU very useful.

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...

Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.

SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.

I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?

im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.

To those that are running OC'd kernels

Is it just my phone that seems to run as smooth or smoother in real world use at the undervolted 1ghz setting? I haven't seen any difference in opening apps and when playing Mega Jump it stutters at 1.2ghz just as much if not more than 1.0ghz. I'm not complaining in the least as my e-peen has no relation to the speed of my phone. The undervolting is also an added bonus of running the 1ghz setting. Coupled with Juice Defender and a few battery concious settings my phone is lasting crazy long. I'm running Bonsai's stock Genocide kernel at 1ghz conservative. When I was on ACS I think 1.2ghz my have been a bit smoother.

Yes i believe its just the kernels that are out right now...
i think they recommend 1000-1200 IF you want to OC but im not sure

As Randy pointed out in one of the Bonsai threads, much more battery is saved by lower operating freqs than by undervolting... 1000-1200 will drain the battery faster than 200-1200, even with the undervolt at 1000.

I have noticed just the opposite of your OP. Running at 1000 I find that some of my games are a tad choppy at times. Going up to 1200 and they are smooth.

To be completely honest, I run at 100-800MHz on the SFR rom, no hiccups or lag differences between 800MHz and 1000MHz that I can tell, so why not run it at 800MHz.

what are your OC scaling?
Ondemand or Conservative?

100-1ghz Conservative (as recommended in the Genocide thread)
100-1.2ghz On Demand when I was running ACS.

I have personally found that setcpu is my phones nemesis. I get waaaaay better battery life and crazy better performance running genocide 0.2a 100-1200 "stock" than running any combination of settings / parameters, other versons of same kernel, or even another kernel for that matter.

Bonsai rom uses genocide kernel? I thought it was it's own custom kernel, I'm on bonsai 3.0.1 with the bonsai 3.0.0 kernel and gpu performance is much improved over stock, running @ 1.2Ghz and much improved battery life over stock eb13.

Its an optimized version of Genocide from my understanding

Ok, I've never read that anywhere before and my first thought was.....you switched out the kernel for genocide and thus caused your own performance issues.

No bonsai is not the same as the genocide kernel at all. Its their own kernel that they made.

Apologies in advance if I misinterpreted your statement (it's a bit ambiguous).
If you set it in SetCPU, then got rid of SetCPU, the change will not stick. Any settings done through SetCPU do not make permanent changes to startup scripts, but are instead applied by the SetCPU application. To make them persist, the "Set on boot" checkbox must be checked, and when this is the case, SetCPU simply does its thing quietly in the background as a service.
If, instead, you modified startup scripts to set CPU speed and governor, well, then, never mind

No, I got you. I've heard of people changing scripts in lieu of SetCPU. I just had read somewhere by one of the devs that if you set it to the 1ghz setting and remove SetCPU that the undervolting would stick. I though it would be the same for clocking. Either way my phone seems t be running very smooth without it so I'm ok with that.

[INFO] Custom Kernels & Overclocking - FuguMod Ultra Pre Release

After reading through the Thread for the Pre Release of FuguMod Ultra in the development section of this forum I thought I would post some info up for people who are wondering why it doesn't work with their phone, and just some general info on overclocking.
- First off, not all phones will be able to run at 1366MHz. Every CPU made has a range of freuqencies it will work at, and it is different for every single one. So some may be able to handle 1366MHz and above, others may max out at 900MHz. If you are getting black screens, freezes, or random behaviour, then your CPU doesn't like the frequency you have it at, try a lower frequency.
- Always keep an eye on the temp of the CPU when testing overclocking, if the CPU gets too hot, and fail safes don't work, there is a chance you could fry your CPU.
- With the FuguMod Ultra kernel, you must also be aware that gpu bus frequencies have been changed, so if your phone is not happy with that it will black screen. (as bus speeds are like cpu speeds, every different device can handle different clock speeds)
- plls values have been changed, and these may cause problems on your phone.
So if you want to have a go at overclocking your phone, back it up, and then give it a go. Select a frequency, and test with something pretty cpu intensive (3d game, multiple quadrant passes) and see if there are any bugs/overheating during a 15min time period. If you notice any problems/too much heat, try a lower frequency, and try again. And if for some reason your phone doesn't like the kernel, you can reflash with your previous kernel or a new ROM as you have already backed up your data.
If you have any other questions about overclocking, feel free to post here and I will try my best to answer them.

The battery temp is a good representation of how hot the processor is getting as it is right next to the battery (only a thin sheet of metal seperating it) If the battery rises in temperature by a few degrees, then you can summize that the cpu is probably getting a few degrees hotter than that. I really wouldn't recommend letting the battery get above 55degrees (celcius) as this means the CPU may be getting up close to 65degrees (celcius) which is a very bad thing.

Good post.
Note that if you want to make some stress-tests, you have to put "PERFORMANCE" governor and set the max freq you want to test.

How have you got your phone set up? i.e. what ROM are you using etc.

I am using stock jpq with app2sd, swap, zipalign, ramhack and stuff. Setcpu is installed with default min/max freakquency, No profiles in use and undervolt a bit.

Ok,
This may be an issue caused by XXJPQ, as it is a new release there may be some sort of conflict. Have you tried asking if anyone else has this issue in this thread? http://forum.xda-developers.com/showthread.php?t=1132697
I haven't played around with JPQ yet so don't know what the bugs are yet.
Also, are you running a stock kernel? Have you confirmed that the phone has been rooted properly as well?

It's definitely a bug in Kernel. I tried three different roms and i wasn't able to check time in state in any of them (I am talking about fugumod ultra prerelease kernel here).
With previous versions of fugumad kernel everything is fine. So definatly a bug in kernel.

Ok cool, I'll report the bug to the developer so that he can have a look into it. Thanks for testing and proving to the kernel.

Little bit of info some might find helpful. After some recent testing, I have found that some people might experience a black screen freeze when phone is in standby for a while with 83MHz min setting and on demand governor. I am not sure of the exact reason for this, whether it is a bug, or that the processor just doesn't like going that low for extended periods of time. If you experience this type of error, just hard reset the phone then open setcpu after phone has loaded and change the "standby" profile minimum to at least the next step up on the slider. Personally I use 223 setting as it provides a smoother lock screen animation, and no significant difference in battery drain.

How safe is overclocking?

I am experiencing lag on real racing 3, on high graphics. If I overclock to say 2ghz on cpu, will the tablet be stable enough? Should I undervolt ( and does it actually make any difference on temps)? I want to overclock but not at the cost of huge battery drain, can some1 recommend me a good kernel and some stable oc steps?

Are you running a custom ROM and kernel? I play RR3 daily and have NO lag. AOKP PUB ROM with ktmanta kernel, at 1.7mhz CPU and GPU OC to 720. Runs great.
Most OC is safe, issues are really with battery and overheating. I've run for long periods at 1900 just fine.

So there's no way the tablet will melt down because of the heat? Does warranty cover that? Assuming they don't know it was overclocked, which they couldn't because the device would be dead, right? I guess they don't bother to repair it and see if it was rooted.
LE: btw did you manage to safely undervolt? Even a -5 gives me reboots on most freqs.

Any time I try to use the app from the store to set the graphics mode it causes problems. Running RR3 without it works fine.

Take a look at the KTmanta thread. KTmanta is a great option for what you are after, he notes and codes distinctions between clocking and thermal protection, plus unless you lock the settings, they will reset at reboot!
If you tell Google you messed it up from some sort of tinkering, no - they won't help you.

I am assuming you must be using the KTmanta kernel right? I thought it was the only kernel right now that allows for user control undervolting. Trinity has a static -50mv value set on all frequencies by default. You should be able to undervolt just about everything. Getting lockups at -5mv lets me think there is something you are not doing correctly

[Guide] Get rid of lag in games / Interactive gov is bugged!

Hi guys,
I have the 855 version of this phone, and I have noticed that, even if Antutu scores are spot on (44k), in games such as GT racing 2 or similar I get a lot of lag.
Now, everyone will think "there are 1000 threads about lag, stick to those". Unfortunately, tricks such as getting rid of the thermal protection are really not good options, as the phone temperature will start to skyrocket.
There's a much easier and safer solution: root the phone and change the governor from interactive to conservative.
With interactive gov and CPU temp open in the background, I have noticed the CPU frequency bounces continuously up and down between 300mhz and 2400, even if the CPU temp is only 55c or so. This is causing the lag! Interactive governor is severely bugged, and this happens with any rom (I have tried both the stock 20h and the ChupaChups 4.2) and kernel (non AOSP at least).
Then, I switched to conservative, launched the game again, and guess what....now the frequency is nicely stable at 2457mhz throughout the entire gameplay and lag is gone completely. Temperatures? Totally fine: max 60c while playing and usually between 35 and 40 while whatsapping.
I literally tried everything to get rid of this damn lag, and the only thing that worked before this solution was to use a different kernel (chupa chups 2.1) and changing the governor...but I was getting crazy high temperatures, that sometimes touched 80c, and this was with a very heavy undervolt too! So I recommend to use the stock kernel, because it's the only one - for me at least - that grants good performances (and by that I mean no lag in games whatsoever and constant 2450mhz while playing) with good temperatures.
Any other option, including undervolting and trying different kernels didn't work for me, because either the CPU frequency kept shifting up and down every second causing lag, or - when I managed to keep it stable using different kernels and undervolting - the CPU temperature while playing got way too high (70c+, touching 80c sometimes).
To sum it up
1) Stick to stock rom and stock kernel (because of temperature issues)
2) Root
3) Change governor from interactive to conservative with Trickstermod (busybox required)
4) Enjoy smooth gaming experience and very good temperatures, with no significant throttle whatsoever!
Hope this helps!

as far as i know, conservative puts the cpu speed into the lowest possible, thus i thought won't be good for gaming performance.
nevertheless, i'd try for a few days and see if there's any noticeable difference.
thanks for sharing the knowledge, OP!

Theoretically you are right. But...interactive is bugged. Ondemand doesn't work (it will make your phone freeze) and performance will drain too much battery. So we are pretty much left with conservative.
Give it a try, and when you do, make sure you have CPU temp open to monitor both temperature and cpu frequency!
Let me know

Thank you! It really did the trick, gaming became MUCH better.
I tried RR3 - it became a lot better. On interactive it lags even in menu, on conservative it's rendering at 23-30 fps with slight not-game-breaking lags.

Battery
And about the battery? Will drain more in conservative than interactive? And will speed up the phone in all app or only in heavy games, when cpu is more active?

I wouldn't worry about battery life..

It seems that this working generally, phone is much snappier and smooth for me than on interactive.

Yeah...the reason is that LG did an awful job with the interactive governor, and what's even worse is that it's actually using it as the default one.
Pretty incredible how bugged this is.

Yes but I think it's possible to make script in init.d folder to run conservative on boot as default. Maybe someone make one.

I Will try this ☺only for curiosity! I need busybox installed too or trickstermod only?

I've been doing the same thing for a long time now. I use SetCPU to automatically switch to the performance governor whenever the screen is on, and interactive whenever the screen is off.
You may also want to consider disabling mpdecision and thermald also. One of the two (probably mpdecision) will regularly change the governor back to interactive if you don't.

That works to get rid of the lag...but my phone was reaching easily 80c.
Now, with everything stock, the frequency stays nicely at 2457mhz with no throttle at all and the in-game temperature only maxes out at 63/64c.

Thanks for sharing this brother...just switched to conservative in trickster and I'll see how it goes.
I'm on crash Rom stock kernel with thermal mod activated...
Don't have any temperature issues till now expert while playing heavy games for some time.
Thanks again

Are the settings in trickstermod applied as you change the setting ? Or do you need to apply them manually ?
Also, do they apply on boot ?

On the latest trickster version you hit the upper right settings icon and the first four option that appear are under the set on boot part.check the kernel setting to be set on boot and you are done.
